Building A Michelson Interferometer

Building A Michelson Interferometer

The Michelson interferometer is a device that uses optical intereference to measure extremely small distance variations. First invented in the late 19th century, it remains in active use today; in 2017,  the Nobel Prize in Physics was awarded to the LIGO experiment for using large-scale Michelson interferometers to detect gravitational waves. Recently, our team at SPMS set out to construct a Michelson interferometer for science education and outreach. Read more
